I am at my wits end with my 5 year old daughter. She is constantly doing everything I repeatedly tell her not to do, like kicking her brother's ball around the living room. She talks back to me and her step dad and gives us dirty looks if we tell her no about something. I have tried sitting down and talking to her. It doesnt seem to sink in. I have tried yelling. That doesnt work either. Time-outs dont work with her- she just goes right back to doing whatever it was that she got in trouble for in the first place. My husband and i dont know what else we can do and now he is threatening to leave if she doesnt change soon. We have been dealing with this for 2 years now. What can i do to make my daughter listen and respect us?
